24C02C-E/MS

Memory IC Overview

The Microchip Technology 24C02C-E/MS is a 2-kbit (256 x 8) serial EEPROM utilizing I2C interface technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 100 kHz, with an access time of 3.5 µs. The device features a maximum active read current of 3 mA and ensures data retention for over 200 years. It is housed in an 8-lead MSOP package and functions reliably across an industrial temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports standard I2C bus communication protocols with Schmitt trigger inputs for noise suppression.
• Includes hardware write-protect functionality for the upper half of the memory array.
• Features fast page write capability with a 16-byte buffer to optimize write performance.

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics with limited pin count constraints
• Embedded systems needing configuration parameter retention

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature grade (-40°C to +125°C) compared to commercial variants. Confirm the '/MS' designation corresponds to the 8-lead MSOP package type. Ensure compatibility with system voltage levels strictly between 4.5 V and 5.5 V. Check for RoHS compliance status in the latest datasheet revision.

Memory IC Selection Notes

Select this component when an I2C-compatible EEPROM with industrial temperature rating is required. The 2-kbit capacity suits applications storing small datasets like calibration values or user settings. Consider the MSOP package for space-constrained surface-mount designs. Verify that the 100 kHz clock speed meets the system's timing requirements.

Memory IC Part Context

This part belongs to the 24C02 series of serial EEPROMs from Microchip Technology. It shares architectural similarities with other members like the 24C01 and 24C04 but offers specific 2-kbit density. The E-series denotes industrial temperature operation, distinguishing it from commercial grade parts. It is widely used in legacy and modern embedded designs requiring reliable non-volatile storage.

Memory IC Replacement Considerations

Direct substitutes include the 24C02C-I/MS for identical electrical specifications with potentially different packaging tolerances. The 24C02C-E/P serves as a through-hole alternative. Cross-brand replacements require verification of I2C address bits and voltage compatibility.
